Product details

It delivers 121 kA breaking capacity at 240 V AC, stepping down to 75.6 kA at 415 V and 52.5 kA at 440 V — numbers that tell you this breaker handles high-fault utility feeds or transformer secondaries without cascading upstream.

Current ratings and thermal derating

Rated 125 A continuously at ambient up to 50 °C. Above that the thermal trip starts pulling back: 122 A at 55 °C, 120 A at 60 °C, 117 A at 65 °C, 114 A at 70 °C.

The 121 kA at 240 V is the headline number, but the real-world SCCR you care about for a 400 V panel is 75.6 kA at 415 V.

Factory-fitted with 2 auxiliary switches (HQ type) and an undervoltage release (UVR). No ground-fault module, no communication function, no voltage trip indicator. If you need shunt trip or ground-fault, this isn't the variant.

Frequently asked questions

What is the breaking capacity of 3VA1112-4EF32-0CC0 at 415 V?
